My hypothesis has been confirmed! I achieved an absolute jump by loading a register with an address and jumping to the location pointed to by that register. Thanks.

just out of curiosity, why use inlie ASM at all? why not just use a function pointer like this:
Code: Select all
typedef void (*func_ptr)(void);
func_ptr f = (func_ptr)0x200000;
f();
this will compile down to:
which seems pretty reasonable...

I knew of no other method at the time. Now that I'm moving onto multitasking, even your function pointer idea will be obsolete because then I'll just have to set the EIP of my processes accordingly.
